Police officers searching for a missing teenager in Perth have found a body.

Kathleen Harkin, 15, was last seen on the banks of the River Tay near Woody Island in the North Muirton area at around 9.30pm on Saturday.

Specialist units including the Scottish Fire and Rescue Service, a dive and marine unit and a police helicopter were deployed to search the area of Woody Island and along the river from Scone Palace to the bridges in Perth city centre.

Perth Police have now found a body in their search, according to local reports.

"We are using specialist resources as it is a difficult and dangerous area to search.

"I would ask that residents in the North Muirton area please check any outbuildings or sheds they may have.

"We are aware of speculation on social media and want to stress that this is very much an ongoing missing person enquiry and any speculation is unhelpful and could cause added stress for Kathleen's family.

"We ask that anyone with information as to Kathleen's whereabouts please contact police on 101."
